We could just replace them with an APP on the smart thingy. Make each vote a direct vote.
Have a monthly program where full time .gov people explain the challenge and each party gets to give their cause-effect-action statement which you can then vote on.
Make it a game show like thing on TV publicly, who knows people may prefer it. They seem to watch all manner of other rubbish.
I prefer the game show type of theme, the equivalent of the Muppet Show, each party would do a sketch on a particular policy issue and the public would vote accordingly. The Upper House could be represented in turn by Statler and Waldorf giving incisive appreciation from their balcony.
No matter what policy position 'Animal' took would get my vote.
